Q: What kind of surface preparation do we need for the use of Loctite products?A: For Loctite threadlocking and many sealing compounds, as received surfaces with thin films of oil are acceptable. Only the removal of heavy grease or contamination is necessary to achieve adequate adhesive performance. Generally, the end user should try to use the least complicated surface treatment required. An outline for testing surface treatment is available on the Loctite Technical Data Sheet.
Q: Should I use a primer for curing Loctite Anaerobics?A: The Loctite threadlocker will cure on metal surfaces without a primer. Changes in a cure speed and percent cure will result from the use of primers and, therefore, primers may increase or decrease the strength of products slightly. Therefore, primers are only recommended for use on non-metallic surfaces with Anaerobics to achieve a practical cure speed.Q: How much adhesive do I need?A: Only enough to fill the bondline. Use of excess material will be wasteful and can lead to migration, causing clean up problems.
Q: How can I stop Loctite products from running out of the joint?A: The most important aspect of this problem is using the proper application technique. Minimal amounts in the proper place will minimize or eliminate migration.
Q: Is this threadlocker corrosive?A: Generally, Loctite products can be considered to be non-corrosive.
Q: What solvents can I use to remove liquid Loctite materials?A: Most organic solvents are effective in removing anaerobic adhesives. Chlorinated solvents are most commonly used.
Q: How can I remove a fastener that is "permanently" locked in?A: The application of heat is needed to remove a fastener that can't be removed with a hand tool. A temperature of 325F and above is needed to break down a standard anaerobic, 500F for high temperature Anaerobics. A heat gun or propane torch is commonly used to do this process, and careful disassembly should occur while parts are still hot. Once apart, and cooled, use methylene chloride (Chisel #79040) to remove cured excess material. Always wipe down the fasteners with clean up solvent to remove the wax film that Chisel leaves on the surface.
Q: Will my bonded parts stay together 5, 10, 20 years from now?A: Testing long term durability is a difficult matter and there are many methods of accelerating bond life testing. Some of these are exposure to elevated temperature, heat fatigue, and humidity exposure. The only way to be absolutely sure that the parts will stay together for a ten-year period is to age parts over that extended period of time. The best way to estimate bond aging would be to compare new products to known quantities and determine ratios of performance in elevated aging tests. The longer and more critical the bond life, the more important the testing is.
Q: How long do I have to wait before I put my bonded parts into service?A: Loctite Threadlocking products show evidence of cure within 15-20 minutes and can resist vibration within an hour.
Q: How long does it take for an anaerobic adhesive to dry?A: Anaerobic adhesives do not contain solvents, which must dry. For an anaerobic adhesive to cure, it must be in contact with active metal ions and contact with oxygen eliminated. Outside of a bonded joint, anaerobic materials will not completely cure.
Q: What are materials that are considered "active" and "inactive"?A: The list is as follows:
ACTIVE Iron, Plain Steel, Nickel, Copper, Manganese, Kovar, Commercial Aluminum (with copper content e.g. 6061), Brass, Monel, Bronze
INACTIVEPlated Parts, Anodized Aluminum, Titanium, Stainless Steel, Galvanized Steel, Zinc, Pure Aluminum, Cadmium, Magnesium, Magnetite Steel, Iconel, Silver, Gold, Natural or Chemical Black Oxide
Q: Why isn't the container full of threadlocker?A: The containers are filled halfway because air is needed in the package to prevent the Anaerobics from solidifying.
Q: Why is the threadlocker colored blue?A: Many times Loctite anaerobic materials are called the red stuff or the blue stuff. With threadlockers, color are selected to designate strength. Generally red means high strength and blue means moderate strength. Other colors do indicate strengths in relative areas.
Q: What are Loctite products compatible with?A: Loctite anaerobic products are resistant to a wide range of fluids, gasses, and environments. Data can be obtained from Loctite's "Fluid Compatibility Chart" (LT-836B).
Q: Whom should I contact if a Loctite product is is involved in a medical emergency (i.e ingestion of, severe reaction to, inhalation of, etc.)?
| A: | First Aid Measures | |
|---|---|---|
| Ingestion: | Do not induce vomiting. Keep individual calm. Obtain medical attention. | |
| Inhalation: | Does not apply. | |
| Skin Contact: | Wash thoroughly with soap and water. | |
| Eye Contact: | Flush at least 15 minutes with water. Obtain medical attention. | |

Q: Are Loctite products toxic?A: Generally, most Loctite products have minimal toxicity. They are nonpoisonous and generally are classified as mild skin sensitizers. Occasionally, people with sensitive skin will show slight irritation after long term exposure to Loctite products. If you have additional questions about health and safety issues please contact Loctite's health and safety departmen.
Q: Do Loctite products contain trichloroethylene?A: No. Loctite Threadlocker 242 does not contain trichloroethylene.
